# I place you back on the ground

My infix spells an alphabet,
And can put things to action
My prefix means to criticise,
And undo or inaction

My postfix is a sound
And to a plant, it is bound
As a verb I am found
I place you back on the ground

Who am I?

Hint:

No letter is repeated in this word

The answer could be:

Disembark.

My infix spells an alphabet,
And can put things to action


This could be Em, the letter 'M', and the prefix for putting things to action. (eg. Empower)

My prefix means to criticise,
And undo or inaction


This could be Dis, as in 'diss', to criticise, as well as the prefix to remove or revert.

My postfix is a sound
And to a plant, it is bound


This could be Bark, as in tree bark, and the sound.

As a verb I am found
I place you back on the ground


Hence, Disembark, as in disembarking from a vehicle, or to be put back on the ground.
